  Introduction: In defense platforms such as submarines, ships, aircraft, and land vehicles, noise and vibration directly affect stealth, communication, and crew comfort. Excessive structural-borne or airborne noise can compromise operational effectiveness and even risk detection in naval operations. To prevent this, defense projects mandate SBN & ABN testing as per MIL-STD-740, MIL-STD-1474, ISO 10816, and ISO 3744 . This blog explains what SBN & ABN testing means, why it’s important, and how Indian defense suppliers can achieve compliance. 1️⃣ What is Structural-Borne Noise (SBN)? Noise generated by mechanical vibrations transmitted through the structure of equipment (e.g., pumps, motors, gear systems). Measured as vibration levels that propagate through structural paths. Critical in submarines and naval vessels , where vibration must be minimized for stealth. 2️⃣ What is Airborne Noise (ABN)? Noise radiated directly into the air from equipment. ...

Introduction: Defense equipment must perform reliably in the harshest conditions — from deserts and mountains to high seas and aerospace missions. To ensure this, the U.S. military developed MIL-STD-810 , a standard that defines a wide range of environmental tests. For Indian defense suppliers, MIL-STD-810 compliance is a mandatory requirement before equipment is accepted by the Army, Navy, or Air Force . This blog explains: What MIL-STD-810 is Key tests involved How Indian companies can achieve compliance 1️⃣ What is MIL-STD-810? MIL-STD-810 is an environmental engineering standard that defines test methods for equipment reliability under real-world conditions. It focuses on: Durability under mechanical stress Resistance to temperature, vibration, shock Performance in extreme environmental conditions 2️⃣ Why MIL-STD-810 Compliance is Important Defense Qualification – Ensures equipment is accepted in military projects. Proves Reliability – Shows ...
